abstract = {This minipaper lays some groundwork for the application of information theory as a measure of the degree of quantum correlation or entanglement. From very early in the project, Everett thought that Shannon information theory (Shannon and Weaver, 1949) would provide insight into pure wave mechanics. Although statistical measures, such as standard deviation, would have sufficed, Everett developed information theoretic measures to represent such things as the width of distributions and the degree of correlation between the states of multiple systems. He thought that the standard quantum uncertainty relations were best expressed in an information theoretic way. There are two versions},
